12 Claims, 17 Drawing Figures CONSTRUCTION ELEMENT TOY BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to construction toys.

2. Description of the Prior Art Construction elements that can be fitted together in a variety of manners make educational and interesting toys. Generally, construction elements designed for small children have been in the form of blocks that can be stacked or otherwise joined. Construction elements of other than block shapes can provide novelty that makes them especially interesting. However, such elements should be versatile to enable their joining in a variety of different manners and configurations. The elements preferably should be easily joinable to one another or to another type of element such as a block.

Block type elements generally can be easily formed by injection molding of plastic type materials. Economical shipment and storage is facilitated if the blocks can be originally formed in a substantially flat configuration and if they can be readily assembled by a child to a block form. If the assembly of the substantially flat device into a block form can be performed in an entertaining manner, as by the different parts easily snapping together into a sturdy block without unsightly overhanging portions, then the entertainment value of the construction element can be further enhanced.

OBJECTS AND SUMMARY OF THE INVENTION An object of the present invention is to provide construction elements which are of a novel, versatile and highly entertaining form.

Another object is to provide a construction element that can be molded in a substantially flat shape and assembled by a child in an entertaining manner into a solid-appearing object.

' In accordance with the invention, cup or cone-shaped and block-like toy construction elements are provided which can be joined into interesting shapes. The cup-shaped construction element has a tapered body with a narrowed end and a wide end, each end having recesses and projections for coupling to other construction elements. The recesses at the wide end are formed by a pair of concentric flanges that extend axially from the wide end to form a groove that can receive projections. The cup-shaped elements can be joined together by inserting a projection at either end into a recess at either end of another element, or by stacking the cups in the same manner as paper cups are stacked.

The block-shaped construction element is formed from a substantially flat member divided by living hinge areas into six face portions, the member being foldable at the hinges into a block. In order to allow the edges of the face portions to lock onto one another, each edge has an inwardly extending rib at one region and a recess at another region. When a pair of face portions is maintained perpendicular and with adjacent edges, and the rib of each edge is engaged in the recess of the other edge, the edges cannot readily separate and the block is locked in configuration.

The novel features of the invention are set forth with particularity in the appended claims. The invention will be best understood from the following description when read in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 illustrates a cone-shaped or tapered cup-shaped toy construction element 10 and a block-shaped toy construction element 12 made in accordance with the invention, showing one manner in which they can be joined together. The coneshaped element has a hollow body 13 in the form of a truncated cone with a wide end 14 and narrow end 16. The wide end 14 has three projections 18, 20 and 22 and a recess 24 divided into three parts by the projections. The narrow end 16, also shown in FIG. 2, has a pair of projections 26, 28 and a pair of recesses 30, 32. Each of the five projections and all of the recesses are formed so that when a pair of identical coneshaped elements are to be coupled, any projection of one con struction element can be received and tightly held in any recess of the other element. The block 12 is constructed with a pair of recesses 34, 36 in each face for receiving the projections of a cone-shaped element. The block recesses or apertures 34, 36 are spaced apart by the same distance as the projections 26, 28, at the narrow end of the cone-shaped element so that a strong coupling can be made to a single cone element.

The cone-shaped element is designed for very versatile coupling. The recess 24 at the wide end is formed by a pair of axially extending flanges 38, 40 which are concentric with the axis 42 of the cone-shaped body. Each of the projections 18, 20, 22 at the wide end lie in the recess 24 formed by the two flanges 38, 40 and they project axially therefrom. The two ring-like flanges 38, 40 provide a large region where projections can be received, to facilitate joining of construction elements in a wide variety of configurations. The two recesses 28, 30 at the narrow end of the cone-shaped element are elongated, which allows a pair of cone-shaped construction elements that are joined at their narrow ends to pivot a limited angle, such as 30 relative to one another. The cone-shaped construction elements can be joined not only by inserting a projection into a recess, but also by stacking, wherein the narrow end of one element is inserted into the hollow space 44 of the body 12 of another element, as illustrated in FIG. 13. In order to avoid binding during stacking, which could prevent a child from easily pulling one element off of another, the elements are provided with a step 46 near the wide end that limits the distance that one element can be received in another. The step 46 also stabilizes one stacked element on the other so that a large number of elements can be stacked without readily toppling over.

FIG. 5 illustrates a flat member 50 that can be assembled into a block-shaped construction element of the type shown in FIG. 6. The substantially flat member 50 has five linear folding regions 52, 54, 56, 58 and 60 of reduced thickness that essentially divide the flat member 50 into six face members or face portions. The six face portions 62, 64, 66, 68, 70 and 72 can be moved into the position shown in FIG. 6 to form the block. Each of the face portions has a pair of apertures 34, 36 with an inwardly extending flange 74 about each aperture to provide a greater area of contact with a projection to hold it therein. Each of the flanges may be provided with a break 76 to facilitate deflection to more tightly engage a projection, although such a break is not necessary. The member 50 may be constructed of a material such as polypropylene which forms a durable hinge at narrowed areas thereof, such a hinge generally being referred to as a living hinge.

In order to hold the six face portions of the member 50 in a cube configuration, the edges of the face portions are designed to tightly coupled or lock to each other. Each of the free edges is provided with an inwardly extending rib 80 and a recess 82 for receiving the rib from another edge. FIG. 7 illustrates the manner in which two edge portions A and B of face portions 72 and 64 are locked together, edge portion A having a straight outer edge boundary 73 within which all parts are contained and the edge portion B having an outer edge boundary 65 within which all of its parts are contained. The rib 80A lies even with the boundary 73 and extends inwardly from the inner surface 721 of the face portion 72 by a distance approximately equal to the average thickness t of the face portion 72. The other edge portion B has a recess 82B which is designed to receive the rib 80A. The recess has a maximum depth 2t equal to the length of the rib 80A as measured from the outer face of the face portion 72. Thus, when the rib 80A is received in the recess 828, a neat comer is fonned wherein the rib 80A is flush with the outer surface of the face portion 64.

In order to prevent the face 64 from swinging out in the direction of arrow 84, a step or flange 86B is provided which extends along the inside of the recess 82B and which can be engaged by the rib 80A. The flange 86B has an outermost surface 878 which is substantially even with the inner surface of the face portion 64. If the rib 80A is thicker or thinner than the face portion thickness t, then the surface 87B should lie slightly behind (inward) or in front (outward) of the. inner surface of face portion 64, respectively. In a similar manner, a rib 80B of the face portion 64 is received in a recess 82A of the face member 72. When the two ribs 80A and 80B are engaged in the recesses 82B and 82A, respectively, the two face portions 72 and 64 cannot be readily separated. Separation generally requires that the ribs 80A and 80B bend slightly to pass over the steps 86B and 86A. While such disengagement can be performed by pulling hard on the face portions, the face portions tend to remain locked together. Thus, once the construction element is assembled, it tends to remain in a block shape.

The substantially flat member 50 which contains the six face portions, can be injection molded in a flat configuration, and shipped and stored in this configuration to conserve space. The child or an adult can assemble the member into a block shape. Not only is space conserved, but the clicking sounds produced during assembly and the ease of folding from a flat to a block shape makes the assembly an entertaining activity. The substantially flat member 50 can be formed with face portions that are of unequal length, to form an elongated instead of cube box-shaped construction element. It is also possible to provide triangular shaped face portions to form a pyramid, or other shaped portions to form a variety of other solid appearing objects.

FIG. illustrates a construction element 90 which utilizes a rotatable device 92 to further its versatility. The member 90 is similar to the construction element shown in FIG. 5, but two faces thereof have large apertures 100 for receiving discs 94 and 96 of the rotatable device. The two discs 94 and 96 are held together by an axle 98 to which they are fixed. It may be noted that each disc has an outer portion 99 of a diameter approximately equal to that of the aperture 100 in a face portion, and a larger diameter portion 102 that bears against the inner surface of a face portion of the cube. The rotatable device 92 can be installed prior to snapping the face portions of the cube together, and it thereafter remains in place.

FIGS. ll-l7 illustrate many ways in which cone-shaped construction elements 10 can be coupled to one another or to block-like construction elements 12. The cone-shaped elements can be coupled to the block-shaped elements by reception of any of their projections in the holes 34, 36 formed in each face portion of the block-shaped elements. The coneshaped elements can be coupled together either by reception of a projection in a recess or by stacking in the manner shown in FIG. 13. The fact that each cone-shaped element has three projections 18, 20, 22 at one end enables it to be removed, rotated and reinstalled, to rotate the projections 26, 28 at the opposite end so they are perpendicular to their original position. This permits construction of a window of the type shown in FIG. 17.
